Abstract
The changes in soft magnetic properties on amorphous Fe73.5Cu1Nb3Si13.5B9 alloy after neutron irradiation are studied by complex permeability spectra, magnetoimpedance ions and M - H curve measurements. The total integration fluence of fast neutrons (nf,En>1 MeV) is varied from 1.92×1014nfcm-2 to 4.85×1016nfcm-2. Two different types of relaxation processes in permeability spectra, which were observed in low and high frequency regions, are related to the domain wall motion and the rotational magnetization, respectively. As neutron irradiation fluence increases, the permeability due to domain wall motion decreases but the permeability due to rotational magnetization increases. The anisotropy field estimated from magnetoimpedance profile decreases with neutron irradiation fluence. The measurement of M - H curves shows the improvement of softness after neutron irradiation of 4.85×1016nfcm-2, due to the enhancement of rotational magnetization.
